Range Card

Trajectory and holdover for airguns

Setup

Rifle and pellet

Velocity in m/s, weight in grain, scope height in mm, ranges in m.

Scope reticle

On a first focal plane scope the subtensions hold at any magnification, so the two × fields do nothing.

Conditions

Wind from: 0 head on, 90 right, 270 left. In the table, + is drift to the right and − to the left.

Card

The target zone sets the point blank window: the stretch where the pellet stays inside that circle without holding over.

Tools
Fit BC from two chrono readings

A fitted BC beats a published one. Measure both readings on the same day, same pellets.

Path is where the pellet sits relative to the crosshair: negative is below. Hold and clicks are what you dial or hold up to put it back on the aim point.
